Definitions

• the object of the present invention are agents for oxidatively dyeing keratin fibers, particularly human hair, which contain certain diaminopyrazole derivatives as developing substance and certain resorcinol derivatives as coupler substance.
• Hair dyeing agents are divided mainly into oxidation dyeing agents and non-oxidative tinting, depending on the starting color of the hair, which is to be dyed, and on the desired end result.
• oxidative hair dyes have attained a significant importance.
• the dyeing is brought about here by the reaction of certain developer substances with certain coupler substances in the presence of suitable oxidizing agents.
• Oxidation dyes which are used to dye human hair, must fulfill numerous requirements. They must be physiologically compatible and provide dyeings in the desired intensity. In addition, the hair dyeings should be highly resistant against the effects of light, permanent waving agents and acids, as well as friction, and remain stable for at least 4 to 6 weeks under normal conditions.
• an oxidative dyeing system must make possible a wide range of different color nuances in the range of natural shades as well as of fashion shades. This means that, on the one hand, yellow, red and blue dyes must be possible for the fashion shade range and, on the other, blond, brown and black dyes for the natural shade range.
• the natural shades can also be obtained by mixing different dyes, which produce yellow, red and blue.
